Rear splined shaft forge die
The utility model relates to forging and stamping field, is specifically related to a kind of rear splined shaft forge die.
Forging is a kind of hot-working mode of production, and it can produce dimensionally stable, and the various product of mechanical performance excellence, is therefore widely used.
Rear splined shaft need in forging process twice shaping, namely first go out embryo, reshaping.The forging method of traditional rear splined shaft be on same equipment first with blocker by whole for raw material ejection, more more mold exchange carries out processing and forming.
Above-mentioned processing method is adopted mainly to there is following defect: due to ejection with shapingly to carry out at twice, the middle time interval is long, need when processing and forming to re-start heating to blank, and need transport back and forth be carried out to blank and deposit, cause the waste of resource and manpower, meanwhile, production efficiency is also very low.
Utility model content
(1) technical problem solved
For the deficiencies in the prior art, the utility model provides a kind of rear splined shaft forge die, makes ejection, is molded on same equipment, synchronously complete in same operation.
(2) technical scheme
For realizing above object, rear splined shaft forge die of the present utility model, comprise working plate, the blocking drift be connected with upper working plate, the finish-forging drift be connected with upper working plate, lower working plate, the base be connected with lower working plate, be connected with base and and the blocker that matches of blocking drift, that be connected with base and and the shaping mould that matches of finish-forging drift, and upper working plate is a bulk metal structure, the symmetrical position of upper working plate is provided with the installing port installing blocking drift and finish-forging drift, during work, blocking drift and finish-forging drift are connected on working plate simultaneously.
The working portion of further described blocking drift is plane.
Further described finish-forging drift also comprises forming punching head, the ram block of working plate and forming punching head in connection.
Further described blocker and base adopt the convex-concave detent form Nature Link having fixed elevation and cooperatively interact.
Further described shaping mould adopts the convex-concave detent form Nature Link that there is fixed elevation and cooperatively interact with base.
(3) beneficial effect
The utility model provides a kind of rear splined shaft forge die, and because blocking drift and finish-forging drift are connected on upper working plate simultaneously, when upper working plate moves with forging equipment, blocker and shaping mould can carry out work simultaneously, substantially increase production efficiency; And blocking blank directly changes to shaping mould after having forged in blocker carry out finish forging, because the time interval is short, need not reheat, effectively save resource.

Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figures 1 to 5, rear splined shaft forge die described in the present embodiment utility model, its structure is: in bulk metal structure, working plate 1 is connected with working end, forging equipment top, blocking drift 3 and finish-forging drift 4 are connected on working plate 1 simultaneously, when upper working plate 1 moves with forging equipment, blocking drift 3 and finish-forging drift 4 can move simultaneously; Lower working plate 2 is the metal that two block structures are identical, and lower working plate 2 bottom is connected with forging equipment bottom stiff end, and lower working plate 2 top connects base 7; As shown in Figure 1, left-hand foot 7 connects blocker 5, blocking drift 3 coordinates with blocker about 5, and after forming, the Preform Die of splined shaft, completes ejection work; Right side base 7 connects into pattern 6, and finish-forging drift 4 coordinates with shaping mould about 6, and after forming, the finish-forging die of splined shaft, completes shaping work.
In the production process of product, the blank that Preform Die is produced is transferred in finish-forging die immediately, add new blank again in Preform Die simultaneously, when upper working plate 1 moves with forging equipment, blocking drift 3 and finish-forging drift 4 move simultaneously, to realize being molded over same equipment in ejection and finish-forging die in Preform Die, carry out in same operation simultaneously.
Meanwhile, the convex-concave detent form Nature Link that base 7 and blocker 5, shaping mould 6 all adopt fixed elevation to cooperatively interact, connects reliable, and is convenient to dismounting.
Obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
